RE: Amendment to Sales Agreement Between Competitive Technologies, Inc. and
Spero Pain Relief Therapy, LLC, dated September 30, 2010

Dear Mr. Miller and Dr. Chalmers,

Based on our discussions, we are pleased amend our agreement with you which is
dated September 30, 2010 as follows:

1.     Spero Pain Relief Therapy, LLC ("Spero"), and its affiliates will, in
selected areas, establish 18 treatment centers utilizing Competitive
Technologies, Inc.'s ("CTTC") Calmare  Pain Therapy Treatment medical device,
model MC-5A.  The original agreement was for 14 clinics.  The 4 additional
clinics are in [Confidential Information Omitted].

2.     Schedule A-1 is amended to include the zip codes for [Confidential
Information Omitted] on Amended Schedule B.  Continued exclusivity is predicated
on Spero's purchase or lease of the minimum number of devices indicated on
Schedule B.

3.     The exclusivity conditions, pricing for devices, supplies and training,
as well as warranty provisions of the original agreement remain in place.

4.     This agreement is transferable and binding upon any new owners in the
event of the change of control or ownership of either CTTC or Spero.

We at Competitive Technologies look forward to a long and mutually beneficial
business relationship with Spero Pain Relief Therapy over the coming months and
years.

Sincerely,
